  1. how much more would it cost if they did a monotube design?
  2. GM factory bed liner is one of the best. It's extremely tough. I've had loads of sharp edged rock dumped into my bed multiple times...the bedliner doesn't seem to mind. Things slide on it quite well too. It is a rough texture and I wouldn't slide anything on it that is softer than the liner. If you want to transport nice wood furniture, etc, put a rubber mat in the bed. I'm honestly amazed that anyone would have any complaints about it.
  3. everyone always ridicules the Rancho shocks in the Z71 package, but I've never once seen anyone explain from an engineering standpoint why. Anyone care to? I know nothing about shocks by the way.
  4. you'll be fine with a 5.3/6spd, but you'll want the heavy duty towing package and the tow mirrors, if you can.
  5. LOL yea, those engineers who work at GM don't know ANYTHING about the engines and trucks they design and produce.
  6. 22" wheels is insane. 18" is the sweet spot, big enough to accommodate good discs and rotors, but small enough to allow lots of sidewall. Sidewall is really important for a truck!
  7. GM 1500 is not "#3 truck" Combine sierra and silverado sales and they are firmly 2nd place, very near to Ford. And both far ahead of Ram.
  8. Both great looking trucks. Personally I prefer the gas mileage and traditional looks of the stock truck, but to each their own!
  9. Hmm. I can feel it. But I'm extremely sensitive to small variations in sensory stimuli. I can hear the tiniest rattle, sense the smallest change in power, etc. If I change tires and they are a few pounds heavier on each wheel, it is obvious to me. It feels heavier and my brain tells me that I have to press the gas pedal just that tiny 3 millimeters more to get the same acceleration. This, of course, is only if I own the car and have driven it for a while.
  10. its rather straightforward. There is a lot more friction inside a new motor than an old one, not to mention the axles, transmission, differential, bearings, etc. As they say, an engine runs best the day before it dies. There is usually a point at which you "notice" the decrease in friction, for me typically around 10-12k miles. It's a nice feeling because you look back and remember what it felt like driving off the lot, and now it feels better. It's part of what creates a bond with a particular vehicle. If you've "broken it in" then I find it hard to let go of.
  11. K2 looks more proportional. Every T1 truck I've seen looks a little "bloated" to me. The cab is a lot bigger, and it makes everything else, especially the wheels, look small. So you get more interior cab space, but its an overall larger volume vehicle now, and it looks it. That said, I do like the T1 overall design. I like the front end and also the rear. It has grown on me. It also seems to look really good with a canopy. The only thing I don't like on the T1 is that swoopy line down the front quarter panel going into the door. Very Mazda, and very un-Silverado like, in my opinion. I wo
  12. less o2, less chance of early combustion, so they can get away with lower octane up high but fuel efficiency will suffer
  13. If you are looking at getting a new bed cover, I have a Trifecta tri-folding cover and its never leaked once in 4 years, and thats in the PNW olympic peninsula with extremely heavy rain. And it was only $300. The problem with the Rev is there are seams going across the cover. Never get anything with seams. My Trifecta still folds in 3 sections but the material just bends with it.
  14. no one would actually tow that trailer up that hill with a gas 2500. Expecting it to somehow breeze up that mountain is fantasy thinking, and imagining the 10 speed would somehow solve the "problem" is also fantasy thinking. The TFL guys rag on the truck like it somehow should've done it faster, but again, fantasy thinking. This is a small block gas V8 pulling a 6600lb truck and a 16,000lb trailer, at high elevation. It's exactly the expected result, and it does not mean the 6 speed is not a good transmission, in any way. Sheesh. Apply some critical thinking! Everyone knows you don't pull extr
  15. I can't figure out how people suddenly decided 6 gears isn't enough. The final drive ratio is similar, and so highway fuel economy is also similar. tractor trailers have 18 gears because the torque requirement is so high, and diesels make huge low end torque so it makes sense to keep the engine down low in the max torque band, especially when taking away from a stop. However in a gas 2500 truck, huge numbers of gears just aren't necessary, or even desirable. The 10 speed may "drive better", but its still a newer transmission, and not necessarily stronger. It also
